【Scope of application】

Mainly used for the tensile strength test of new building waterproof materials (including new waterproof coiled materials, waterproof coatings, waterproof sealing materials, etc.), that is, under the set speed condition, the sample within the gauge length is stretched to measure The force at break can also be used to test the tensile properties of other non-metallic materials.
